From the documentary Alive Inside about "the power music has to 'awaken' minds considered closed," an Alzheimer's patient named Henry is brought to life by the sound of his favorite songs.

Explaining the science behind the "awakening," Musicophilia author, neurologist Dr. Oliver Sacks says, "Music imprints itself on the brain deeper than any other human experience. Music evokes emotion and emotion can bring with it memory...music brings back the feeling of life when nothing else can."
